Todll whom it may concern: v 1 Y Be it known that 'I,,JA1uEs LEVER. RUSH- TON, a subject of the King offGreat Britain,

residing at Kay' Street, Works, Bolton, in

the county of Lancaster, E,ngl and, havev in:-

vented new and useful Improvements in Drawing Mechanism for. BingSpinni'ng Frames andthe like, of which the following is a specification. I

The invention relates to improvements in or relating to.drawingmechanism-"for ring spinning frames-{draw frames and the like and has for'its" object to provide; an lm vf' proved arrangement of rollers whereby yarn can be spun having a higher .draft hitherto while being-freer from irregularities due to. diflerences in the lengths of thefibres according to thepresent invention.

i Figure; azplan-thereof, the back topweighting" roller, the leather-covered front top roller andtheitop flannel-covered clearer or other causes,

For the purpose; of usual roller stand is provided with a. front bottom fluted roller having a-.suitable flannel-covered. clearer roller, a back bottom plain roller and a back top weightin 'roll'er.

Mounted upon the-'-ro ller stand between the back and front rollers is a flat board or the like whose-surface is aligned with the tops of the' saidatwo;rollers, and passed around said back bottom roller and the'said board is an endless'iband or belt 'of leather or other suitable material, said endless belt being maintained-taut by means of a shoe hinged to the underside of thev board and pressed against said endless-belt by a suitably mounted' spring g Mounted in slots-in the, cap bars is a hol flow middle rolleradaptedto rest upon the endless" belt-,7 and likewise; mounted and adapted to rest upon the Iendless'belt at or near to the lower edge ofthe'flat board said lower edge being suitably curved, is a roller covered with rubber, le'ather 'or other suitable material; j I

Also carried by'the cap bars and adapted to press against thefront bottom flutedroller isa leather-covered front-top roller, which is provided with a' fian-nel covered top clearer roller adapted -to' rest upon said front'top roller and the backtop ing roller hereinbefore mentioned.

In a modification of the device the means for maintaining the endless strip tauticomprising a spring-controlled shoe, are sub weightthis invention side of the endless belt and by reason of the lever being weighted said endless strip is maintained 7 taut thereby, while suitable flanges formed upon said lever serve to maintain' 'the lever in its torrect position relative to the band.

,And in order that the-saidinvention may be .clearly i'i-nderstood and readily c-arricd into'efi'ect, I willinow proceed more 'iully :to describe the same aided by the accompanyiiig drawings in which.

Referring to Figures 1, 2 and. 3, 1 represents the roller'stand, 2 the cap bar pivotallymounted.thereon-at3, 4 the roving guide and 5 the thread guidemounted-upon the frame 6 of the machine. 7

Mounted in the 'slots'2 inathei-cap bars 2 is a hollow middle rollerladaptedto rest upon. the endless strip 11, and similarly mounted and adapted to rest upon said strip 11 at or near to the suitably curved lower edge of the board 10, is a roller 15 covered with rubber, leather or other suitable material. I

Also carried by the cap bars 2 and adapted to ress against the front bottom fluted roller g is a leather-covered front top roller 16, provided with a flannel-covered clearer roller 17 adapted to rest upon said roller 16 and the back top weighting roller 18.

In operation the roving 19 passes between the endless belt 11 which is driven by the back bottom plain roller 9, and the back top weighting roller 18, and 1s carried by said endless belt 11 over the board 10 and beneath the hollow middle roller 14 and the leather or rubber covered roller 15, said latter rollers 14 and 15 each controlling fibres of different lengths, and after passing from theendless strip or band 11 the yarn is led between the front bottom fluted roller 7 and the front top leather-covered roller 16 which rollers 7 and 16 effect a final draft which is at this stage considerably higher than heretofore.

In Figures i and 5 is illustrated a modification of the device in which a lever 20 pivotally mounted upon a rod at 21 extending from roller stand to roller stand and provided at one end thereof with a weight 22 and at the other end with flanges or the like 23 is used for maintaining the belt 11 in taut condition, in place of the spring-controlled shoe 12 of Fig. 1. In this form the plate member 10 is of slightly different form from the member 10 of Fig. 1.

As the belt 11'is driven by the roller 9, the lever 20 by reason of the weight 22 bears against the underside of said belt 11 in its passage and the flanges 23 serve to maintain the lever in its correct position relative to the belt.

The roller 9 is provided with a recessed periphery leaving flanges 9 at the ends thereof and the periphery of the roller 18 works within said recess while the flanges of the roller 9 serve as a guide for the endless belt or band 11.

It will be understood that the diameters of the several rollers and the details of construction of the device may be varied without departing from the principle of the invention.

What I claim as my invention and desire to secure by Letters Patent is 1. The process for obtaining a high draft of the yarn in ring spinning frames, draw frames and the like, which consists in passing the roving between a tightly-stretched endless belt and a Weighted roller, then between a hollow roller and said endless belt then between a covered roller and said belt and finally between a fluted roller combination of a front bottom fluted roller,

a back bottom plain roller, a flat board mounted upon the roller-stand, the surface of said board being in alignment with the tops of said bottom rollers, an endless belt of flexible material stretched over and around said board and driven by said back bottom plain roller, means for maintaining said endless band in a taut condition, a back top weighting roller adapted to bear upon said endless belt in its contact with the back plain roller, a hollow middle roller mounted in the cap bars and adapted to bear against said endless belt a covered roller likewise mounted and adapted to bear against said endless belt adjacent to the lower edge of the board, a leather-covered top front roller in cont-act with the front bottom fluted roller and flannel covered clearer rollers in contact with said front top and bottom rollers respectively.

3. In the drawing mechanism of ring spinning frames and the like, the combination of a front bottom fluted roller, a back bottom plain roller, a flat board mounted upon the roller-stand, the surface of said board being in alignment with the tops of said bottom rollers, an endless belt of flexible material stretched over and around said board and driven by said back bottom plain roller, pivoted means in engagement with said belt and adapted to yieldingly maintain the same in taut condition, a back top weighting roller adapted to bear upon said endless belt and maintain it in contact with the back plain roller, a hollow middle roller disposed in position to engage said belt during its passage over said board, a top front roller provided with a covering of flexible material in contact with the front bottom fluted roller, and flannel covered clearer rollers in contact with said front top and bottom rollers respectively.

4. In the drawing mechanism of ring spinning frames and the like, the combination of a front bottom fluted roller, a back bottom plain roller, a flat board mounted upon the roller-stand, the surface of said board being in alignment with the tops of said bottom rollers, an endless belt offlexible material stretched over and around said board and driven by said back bottom plain roller, a pivoted lever in engagement with said belt, means for yieldingly retaining the lever in belt-engaging position thereby to maintain the belt in taut condition, a back top wei hting roller adapted to bear upon bottom fluted roller, and flannel covered said en less belt and maintain it in contact clearer rollers in contact with said front top with the back plain roller, a hollow midand bottom rollers respectively. dle roller disposed in position to engage said In testimony whereof I have signed my 5 belt' during its passa e over said board, a name to this specification.
